When does an anastomotic leak occur?

A leak may be present at the time of surgery, though surgeons can screen for leaks at this time. It’s more likely to occur sometime during the healing process. Most leaks show up within the first week after surgery, but some may occur later. Healthcare providers keep watch for leaks in the weeks following surgery. Smaller, slower leaks may take longer to show their effects. A delayed anastomotic leak, occurring more than 30 days later, is less common.
